lOca. l 20 INVENTOR CLARENCE B-JOHNSON AT TORNEY "FLEE -v United StatesPatent 3,346,908 BRUSH ATTACHlVIENT FOR PRESSURIZED CONTAINER ClarenceBenjamin Johnson, P.0. Box 281, San Bruno, Calif. 94066 Filed Apr. 11,1966, Ser. No. 541,820 6 Claims. (Cl. 15-552) The present inventionrelates to improvements in a brush attachment for pressurized container,and it consists of the combinations, constructions and arrangement ofparts, as hereinafter described and claimed.

An object of the invention is to provide a brush attachment that may bereadily secured to a pressurized container and firmly supported thereonso that contents of the container can be delivered to the bristles ofthe brush, the application of the brush attachment to the containerbeing accomplished with facility and ease.

More specifically stated, it is proposed to provide a bracket having asuction cup secured thereto, this cup being made to be anchored to thecontainer, and the brush having a tubular handle made to be connected toa discharge spout of the container, whereby contents of the latter maybe conveyed to the brush. Moreover, the bristles of the brush arearranged in a position so that the bristles may be used withoutinterference by the bracket.

Another object of the invention is to provide a spring clip on the topof the bracket that is adapted to engage with the handle of the brush soas to secure the brush to the bracket, whereby the brush may be readilyconnected to the bracket or removed therefrom.

Other objects and advantages will appear as the specification proceeds,and the novel features of the invention will be particularly pointed outin the appended claims.

Drawing For a better understanding of the invention, reference should behad to the accompanying drawing, forming part of this specification, inwhich:

FIG. 1 is a side elevational view of my brush attachment for pressurizedcontainer;

FIG. 2 is a vertical sectional view taken along the plane 2-2 of FIG. 1;

FIG. 3 is a view similar to FIG. 1, but disclosing a nipple for couplingthe discharge spout of the container to the inlet end of the brushhandle, this nipple being shown in section;

FIG. 4 is an enlarged sectional view taken along the line 4-4 of FIG. 3,showing a discharge spout that is rectangular in cross-section; and

FIG. 5 is a view similar to FIG. 4, but showing a discharge spout thatis semi-cylindrioal in cross-section.

While I have shown only the preferred embodiments of my invention, itshould be understood that various changes, or modifications, may be madewithin the scope of the appended claims without departing from thespirit thereof.

Detailed description Referring now to the drawing in detail, there hasbeen shown a pressurized container designated generally at A in FIG. 1for holding contents, for instance, instant lather for shaving, but I donot desire to be limited as to the contents. Such a container isreferred to as an Aerosol container in the trade, and it has a dischargespout extending laterally therefrom and through which the contents maybe discharged under control of a valve 11.

It will be noted that my brush attachment is designated generally at Bin FIGS. 1 and 2, and it defines a bracket 12 having a suction cup 13secured thereto by a stud 14 and nut 15, this stud passing through aslot 16 formed 3,346,908. Patented Oct. 17, 1967 in the bracket (seeFIG. 2). This suction cup is made for being anchored to the exteriorsurface 17 of the container A. A foot 18 is provided on the lower end ofthe bracket below the suction cup 13 so as to bear against the containerand steady the bracket, when the cup is anchored to the container.

With reference to FIGS. 1 and 2, it will be apparent that a brushdefines a tubular handle 19 positioned above the bracket 12, and thishandle has an inlet end 20 made to be connected to the discharge spout10 by being telescoped thereover, whereby contents from the container Amay be conveyed to the hollow interior 21 of the brush handle 19. Theslot 16 will permit the suction cup 13 to be adjusted verticallyrelative to the bracket 12 so that this cup may be positioned below thecrimped annular flange 22 of the container, when the inlet end 20 isaligned with the spout 10.

As will be apparent from FIGS. 1 and 2, the brush has bristles 23carried by a ferrule 24 and the latter is telescoped into the interior21 of the handle 19 from the front end of the handle. The interior ofthe handle communicates through a bore 25 with the bristles 23, wherebythe contents of the handle may be transferred to the bristles.

For the purpose of securing the brush to the bracket 12 for supportthereby, a spring clip C is secured to the top of the bracket, forinstance, by a rivet 26, and this clip defines a pair of spaced springlegs 27 made to straddle the brush handle 19 and yieldingly engagingthis handle, as shown in FIG. 2.

As clearly disclosed in FIG. 1, the bristles 23 of the brush projectoutwardly beyond the bracket 12 in a direction opposite to the containerA. The longitudinal axis 28 of the brush is disposed substantially atright angles to the vertical axis 29 of the container A. Thus the brushmay be utilized without removing it from the spring clip C, with theuser grasping the container in one hand.

The discharge spout 10 in FIG. 1 is cylindrical; how ever, Aerosolcontainers are now on the market that have rectangular-shaped dischargespouts 10a (see FIGS. '3 and 4) and semi-cylindrical discharge spouts10b (see FIG. 5).

The brush attachment disclosed in FIG. 3 is identical with the one shownin FIGS. 1 and 2; therefore, like reference numerals have been appliedto corresponding parts. However, in order to accommodate the brushattachment B to the rectangular discharge spout 10a in FIG. 3, a nipple30 made of resilient material has been provided. This nipple has a bore31 extending therethrough, the rear and front portions of this borebeing made to telescopically receive the discharge spout 10a of thecontainer A and the inlet end 20 of the brush handle 19, respectively,whereby the nipple 30 will convey contents from the container to theinterior of the handle.

When the discharge spout 10b for the container (see FIG. 5) issemi-cylindrical in cross-section, the nipple 30 will have a bore 31' ofthis same shape.

In any event, the nipples 30 and 30' will have fluidti-ght connectionswith the discharge spouts with which they are used, and likewise thesenipples will have sung fits with the inlet end 20 of the brush handle.

I wish to stress the fact that my brush attachment B has universalapplication to pressurized containers of various sizes and shapes andmay be accommodated to discharge spouts of different cross-sections.
